★调用实例：
在Winforms的“导出excel”按钮的Click事件填写如下代码：
List
list.Add("员工编号");
list.Add("身份证号");
list.Add("打卡时间");
XPri.Export(dgvData, progressBar1, list);
//list为泛型对象, dgvData是DataGridView控件, progressBar1是progressBar控件。//设置progressBar1.Visible=false;
//员工编号, 身份证号, 打卡时间为dgvData的列的文本HeadText
//员工编号, 身份证号, 打卡时间为需要强制导出为文本的列
★源代码如下:(方法重载文件名：XPri.cs)
